The Z-80 is generally acknowledged to be one of the most
powerful 8-bit microprocessors available, and is used in many
popular microcomputers including the TRS-80, Spectrum,
ZX81 and Nascom machines, etc.
■ This book is intended for people who wish to progress
beyond the stage of Basic programming to topics such as
machine-code and assembly-language programming or need
hardware details of the Z-80 based computer.
■ Starting with a review of computer principles, the book
describes typical machine-code instructions followed by a
detailed description of the Z-80 instruction set. Assembly language programming is discussed with examples.
■ Also given are hardware details of the Z-80 and the use of
associated I/O devices such as UARTs, PIOs and CTCs.
■ This book is not purely a descriptive text, however, Z-80 hex
machine-code and assembler instructions are given in tabular
form, along with in-out connections for the Z-80 and the associated devices. It will therefore also be a useful reference book for
the more experienced user.
